There's still an insufficient amount of evidence to convince this blogger that Apple will soon release a larger iPad, but that hasn't stopped others from speculating.
Apple Insider reports that famed market analyst Ming-Chi Kuo of KGI Securities expects that Apple will launch a stylus alongside the still-rumored iPad Pro.
"Coupled with its unfavorable cost structure, high selling prices may turn consumers off if the 12.9-inch iPad is always bundled with it," he wrote. "We therefore expect the stylus to be an optional accessory before sufficient user feedback is received."
"The addition of a gyroscope accelerometer to a stylus allows users to write not only on the display, but also on other hard surfaces and even in the air," he wrote. "While this is a fantastic application for a stylus, we think the required software and hardware is not fully developed yet. Hence, we don't expect Apple's stylus to support 3D handwriting in 2015."
A stylus would be a great addition to a tablet of any size; that is why Samsung has a stylus integrated into the Note tablets and phablets, and it is also why Axiotron (and later Modbook Inc) integrated a Wacom stylus into the Modbook.
It would be good idea for Apple to release a stylus, especially if it were as technically sophisticated as Kuo describes, but at this point there is still no evidence that is Apple going to release one.
In fact, there's no evidence to support the idea that Apple will release the iPad Pro or a stylus in the second quarter. There have been very few iPad Pro component, specs, diagrams, or statements leaked to the press (and zero leaks about a stylus), and with only 5 months to the end of the window there's not much time for those leaks to happen.
Remember, past Apple products have been leaked profusely and repeatedly with iPhone 6 and iPad Air 2 components showing up as much as 5 months in advance of the launch event.
Just about the only new Apple product which didn't leak extensively was the Apple Watch, and as you may recall that launched last September but has not yet shipped. If Apple follows a similar pattern with the iPad Pro then we won't be able to buy one until sometime about 5 to 6 months after it launches.
If you want one sooner, you could plunk down $2,300 and get a Modbook from Apple's unofficial tablet partner, Modbook Inc. (I plan to do so, right after they mac a Modbook from a Macbook Air.)
Modbook Inc (and its predecessor, Axiotron) have been making Macbooks into tablets since 2007. With a price tag of $2,000 to $4,000, the Modbook is way outside of my price range but there has proven to be a small market for it. Should Apple produce a $1,000 iPad Pro, I think they would sell the dickens out of them.
